Amazon Cognito | Pricing Flashcards
How are conflicts in the synchronization process handled?
Pricing
Amazon Cognito | Security, Identity & Compliance
By default Amazon Cognito maintains the last-written version of the data. You can override this behavior by choosing to respond to a callback from the AWS Mobile SDK which will contain both versions of the data. Your app can then decide which version of the data (the local one or the one in the Amazon Cognito sync store) to keep and save to the Amazon Cognito sync store.
How much does Cognito Identity cost?
Pricing
Amazon Cognito | Security, Identity & Compliance
With Amazon Cognito, you pay only for what you use. There are no minimum fees and no upfront commitments.
If you are using the Cognito Identity to create a User Pool, you pay based on your monthly active users (MAUs) only. A user is counted as a MAU if within a calendar month there is an identity operation related to that user, such as sign-up, sign-in, token refresh, and password change. You are not charged for subsequent sessions or for inactive users with in that calendar month. Separate charges apply for optional use of SMS messaging as described below.
The Your User Pool feature has a free tier of 50,000 MAUs each month. The Cognito Identity free tier does not expire at the end of your 12 month AWS Free Tier term, and it is available to both existing and new AWS customers indefinitely
Federated Identities and secure access control for AWS resources are always free with Cognito Identity.
How much does Cognito Sync cost?
Pricing
Amazon Cognito | Security, Identity & Compliance
Sync charges are based on the total amount of data saved in the Amazon Cognito sync store and the number of sync operations performed. A sync operation compares the local data store on a device to the Amazon Cognito sync store in the cloud and synchronizes the two data stores.
As part of the AWS Free Tier, eligible AWS customers receive 10 GB of cloud sync store and 1,000,000 sync operations per month for the first 12 months. Outside the Free Tier, Amazon Cognito costs $0.15 for each 10,000 sync operations and $0.15 per GB of sync store per month.
What is a sync operation?
Pricing
Amazon Cognito | Security, Identity & Compliance
When you call the synchronize() method using the AWS Mobile SDK, this counts as a sync operation. If you are calling the server APIs directly, a sync operation is initiated when a new sync session token is emitted and is completed with a successful write or a timeout of the session token. Whether you use the SDK synchronize() method or call the server API’s directly, sync operations are charged at the same rate.
What are Monthly Active Users (MAUs)?
Pricing
Amazon Cognito | Security, Identity & Compliance
A user is considered active and counted as a MAU when there is an operation (e.g., sign-in, token refresh, sign-up, or password change) associated with the user during the billing month. Therefore, you are not charged for subsequent operations during the billing month or for inactive users. Typically, your total number of users as well as your number of operations will be significantly larger than your total number of MAUs.
What does it cost to use SMS messages with Cognito?
Pricing
Amazon Cognito | Security, Identity & Compliance
Use of SMS messaging to verify phone numbers, to send codes for forgotten or reset passwords, or for multi-factor authentication is charged separately. See the Worldwide SMS Pricing page for more information.
Is Amazon Cognito part of the AWS Free Tier?
Pricing
Amazon Cognito | Security, Identity & Compliance
Yes. As part of the AWS Free Tier, Cognito offers 10GB of sync store and 1,000,000 sync operations in a month for up to the first 12 months of usage. Your user pool for Cognito Identity is free for the first 50,000 MAUs, and we offer volume-based tiers thereafter. The Federated Identities feature for authenticating users and generating unique identifiers is always free with Cognito Identity.
Does every write or read from the app count as a sync operation?
Pricing
Amazon Cognito | Security, Identity & Compliance
No. You decide when to call the synchronize() method. Every write or read from the device is to the local SQlite store. This way you are in complete control of your costs.
What does push synchronization cost
Pricing
Amazon Cognito | Security, Identity & Compliance
Cognito utilizes Amazon SNS to send silent push notifications. There is no additional charge for using Cognito for push synchronization, but normal Amazon SNS rates will apply for notifications sent to devices.
